Microlife WatchBP Office AFIB Automated Office Blood Pressure Monitor
Dual-cuff, inter-arm difference, AF detection, auscultatory mode - includes M and L cuffs

The Microlife WatchBP Office AFIB (TWIN200 AFS) is a professional automated office blood pressure monitor that combines the advantages of an automatic blood pressure device and a hybrid sphygmomanometer. Designed for clinics, physician offices and hospital use, it takes upper-arm measurements on both arms at the same time to assess the Inter-Arm Difference (IAD), while simultaneously screening for Atrial Fibrillation (AF). According to the manufacturer, its AF detection achieves 98% sensitivity and 92% specificity.

The device supports Automated Office Blood Pressure Measurement (AOBPM), with an optional 5-minute countdown before three measurements are taken automatically at one-minute intervals, similar to the method used in the SPRINT trial. An auscultatory mode allows manual measurement for patients where oscillometric readings may be less suitable, such as elderly, obese or arrhythmic patients. Mean Arterial Pressure (MAP) and Pulse Pressure (PP) are displayed with each reading, and data can be transferred to a PC by USB for review and analysis using free WatchBP software. WatchBP Office AFIB is designed to support office blood pressure measurement in line with European Society of Hypertension (ESH) and American Heart Association (AHA) guidelines.

Frequently Asked Questions

How accurate is the AF detection on the WatchBP Office AFIB?
Microlife reports 98% sensitivity and 92% specificity for atrial fibrillation detection with this device.

What is Inter-Arm Difference (IAD) and how does this monitor measure it?
IAD is the difference in blood pressure between the left and right arms. The WatchBP Office AFIB uses two cuffs to measure both arms simultaneously, allowing IAD to be assessed in a single measurement.

What is AOBPM mode?
Automated Office Blood Pressure Measurement (AOBPM) lets the device run an optional 5-minute countdown, then take 3 measurements automatically at 1-minute intervals, similar to the method used in the SPRINT trial.

When should auscultatory mode be used?
Auscultatory mode is intended for patients where manual measurement may be preferred, such as elderly, obese or arrhythmic patients.

What cuff sizes are included?
Two M-size cuffs (22-32 cm) and two L-size cuffs (32-42 cm) are included, covering most common adult arm circumferences.

Can measurement data be exported?
Yes. Readings can be transferred to a PC through the mini-USB port and reviewed using WatchBP software, which is free to download from the manufacturer's website.
